To all whom it may concern:

Be it known that we, J ArrIUs GEORGE, of Wilcox, in the county of Elk and State of Pennsylvania, and CHRISTOPHER M. SHOR- TLE, of Bernhards Bay, in the county of Oswego and State of New York, have invented certain Anew and useful Improvements in Machines for Making Wire-Glass; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improved machine for making wire glass, the object of the invention being to provide an improved drawing pot through which the wire netting can be drawn and be -evenly coated with glass.

A further object is to provide improved mechanism for drawing the wire glass, improved means for maintaining the glass at the roper temperature, improved means for cutting the glass into lengths, andimproved means for annealing the glass in transit.

With these and other objects in view, the

invention consists in certain novel features .of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in elevation and partly in section illustrating our improvements. Fig. 2 is an enlarged view in section of the drawing pot, takenv at right angles to Fig. 1.- Fig. 3 is an enlarged detail view of the cutting means.

Figs. 4, 5, 5a and 6 are views of details of construction and Fig. 7 is a modified form of draw pot nozzle.

1 represents our improved drawing pot which is mounted in the heating chamber 2 and supplied with molten glass Jfrom the supply chamber 3, by tubes 4 communicating with the ends of pot 1 and in the inlet ends of these tubes 4, plugs-5 are located and have o enings therein to admit the glass. These p ugs can be replaced by others having smaller or larger openings according to the flow desired or can be replaced by solid plugs when the flow is to be cut oil.

The drawing pot 1 is made with an integral elongated nozzle 6 extending from its bottom up to a' point approximating the normal level of glass in the pot and the wire netting 7 is drawn from a reel 8 supported in a chamber 9 below the pot, up through the nozzle 6 to receive, at the upper end of the nozzle, its proper coating of molten glass.

hig electrical resistance is located as shown at 10, and connected in an electric circuit by wires 11, so that the upper end of the nozzle Around the up er end of nozzle 6 an insert of material of l will be maintained at the proper temperature to prevent chilling the glass.

The wire glass is drawn upward between endless conveyers 12 supported in a suitable framework 13 and rovided with ingers or prongs 14 to grasp t e glass and carry it upward. Beside the vertical portion of the heaters in the path of the moving glass, an electrical heater 15 is located to maintain the glass at proper temperature. 4This heater may be made in various ways, one structure being illustrated in cross section in Fig. 6 and comprises an insulated receptacle for a filler of material .of high electrical resistance 16 connected in an electric circuit to maintain the proper temperature about the glass.

The chains at one side carry cutters 17 at regular intervals' to sever the glass into proper lengths. These cutters move on a track 18 which normally holds them out of the path of the glass, and at the point of severance, the tracks bend .sharply to force the cutters through the glass. On the oppof site chains, at regular intervals to reglster with the cutters, electrical heaters 19 are supported to heat the glass before being severed. These heaters 19 are made with metal contacts or brushes 20 which slide on kmetal contact bars or rails 21 to cause said heater to soften the glass entirely across the sheet to facilitate its severance by the cutters. The bars or rails 21 are located adjacent to the path of the moving glass and the electric circuit of all the heaters 19 will be closed as they near the point of cutting to soften the glass at these points and as they pass this point the brushes 20 will move oil' the contact bars or rails and the electric circuit will be broken. The severed sheet of glass will then-be tilted by the bell-cranks 21a onto a conveyer 22 .carried below an endless belt 23 and while supported in this horizontal position is Omoved through an electric heater 24 to anneal or harden the glass.

The belts or conveyers 22 and 23 and might rangement of the parts described Without.

heater 24 constitute an annealin leer shown in detail in Figs. 5 and 5a. The elts or conveyers each comprise a series of blocks or plates having lugs 25 connected by links 26 and form in eii'ect sprocket chains moved by sprocket wheels 27. These blocks orplates in rounding the sprocket wheels are free to separate and when they reach a horizontal position resent a1 lat surface to receive the glass. e ends of the lates of the lower conveyer 22 are provi ed with upturned ianges 28 which space the conveyers apart and form an inclosed chamber or table for the sheets of vglass and hold the latter inproper position while passing through the eater to be perfectly annealed'.

Heretofore wire glass furnished to the trade has a clouded or more or less opaque appearance, While the lass manufactured by our improvements w l be perfectly clear and can be highly polished like any ordinary plate glass.

In the drawings we have shown cooling pipes-29 at the edges of the drawing pot and as shown in Fig. 7 a cooling pipe30 is located in the nozzle when the apparatus is to vbe used for the manufacture of ordinary plate glass. Y'

The details ofthe several electrical heaters may of course be-varied and any construction of material Which will do the work may be em loyed and a great many changes he made in the general form and ar'- departing from our invention, and hence we do not restrict ourselves to the recise dey tails set forth but consider ourse ves at' libl ters-Patent, is
